Crust broken into many pieces called plates the plates move along the soft mantle located below the crust

Plates The plates move along smoothly sometimes they get stuck and pressure builds up

Mantle the largest layer of the Earth made of hot, dense rock that flows like asphalt the temperature differs within the mantle

Mantle The movement of the mantle creates the movement of the Earth’s plates.
